Job Description
The Information Security Engineer (Client) will be responsible for defining, delivering, and supporting the enterprise security tools. 
This role is specifically responsible for building, operating, and continuously improving an LLM-based code vulnerability detection and reporting capability. The initial phase is build: design and deliver the scanner, evaluation harness, and CI/CD pipelines. Once operational, the role shifts to run: patching, tuning, feature development, and sustained operational support. Finding triage and remediation ownership are out of scope for this role.
ESSENTIAL DUTIES & RESPONSIBILITIES:
Serve as a security engineer/consultant on cloud projects. Build and operate an LLM-based code vulnerability detection capability on AWS Bedrock, including prompt/agent design, model invocation patterns, cost and token controls, and result normalization. Develop and maintain the evaluation harness used to measure scanner quality, including regression corpora, repeatable test execution, and reporting on detection performance over time. Build and maintain scanning pipelines integrated with GitHub and Jenkins, deployed to ECS and provisioned through Terraform. Deliver findings and operational telemetry into Splunk; build dashboards and alerting for scanner health, coverage, and throughput. Engineer and implement well-architected solutions while adhering to software development best practices. Advise Principal Engineers and Product Owners on operations and evolution of their product.

• Design, test, and implement solutions at the Feature level.
• Support the Bank's operational information security responsibilities, including the development and maintenance of standards, procedures, and guidelines necessary to satisfy the Information Security department's operations.
• Provide ongoing operational support, patching, and defect resolution for the deployed scanner after go-live.
• Participate in a four-person rotating shift schedule providing 24/7 coverage, including nights, weekends, and holidays. Scheduled hours average 40 per week.
• Maintain appropriate controls and documentation to ensure compliance with all company and regulatory requirements.

• SUPERVISORY RESPONSIBILITIES:  None.
  REQUIRED KNOWLEDGE, SKILLS & ABILITIES:

• 4+ years of related engineering experience, including hands-on information security or software development work.
• Hands-on experience with AWS Bedrock or equivalent hosted LLM platforms, including model selection, inference optimization, and guardrail configuration.
• Demonstrated understanding of Infrastructure as Code best practices and strong experience building Terraform modules.
• Experience building and maintaining CI/CD pipelines, preferably Jenkins, integrated with GitHub.
• Working knowledge of application security concepts, common vulnerability classes, and SAST/SCA tooling behavior.
• Must be able to communicate ideas both verbally and in writing to management, business and IT sponsors, and technical resources in language appropriate for each group.
• Eligible to work in the US without the need for sponsorship now or in the future.
• PREFERRED KNOWLEDGE, SKILLS & ABILITIES:

• Demonstrated experience building on AWS, including IAM, ECS, and service-to-service authentication patterns.
• Experience with agentic or multi-step LLM workflows, including context management across large repositories.
• Experience with RESTful APIs and event-driven architectures.
• Splunk development experience, including data onboarding, search, and dashboarding.
